Permeability is when water can pass through different types of soil and rocks. Therefore the permeability affects the soil and rocks because if the soil or rock is PERMEABLE then the groundwater can easily flow through it :)
A silicon transistor is a transistor made of silicon.
There is not feasible way to change the overall porosity and permeability in an oil field. However, it is possible in many cases to improve the porosity and permeability within the near wellbore region, where the change in pressure is the greatest. Injecting acid into a well, may slightlyincrease the porosity but sigmificantly improve the permeability, as it creates larger flow paths (also called worm holes) through the formation. Hydraulic fracturing will also stimulate a well, although the formation's permeability and porosity is unchanges. It makes it easier for oil to flow into the well, so its effect in the long run, is the same as if the near well bore region had higher permeability. Low permeability formations often produced by horizontal wells, which is similar to hydraulic fracturing- it is easier for the oil to flow to the well.
high permeability ,low hysterisis,increased resistivity
produces magnetic properties,such as small hysteresis area and permeability Hysteresis loss depends upon the material of the core

Silt has neither high or low permeability. It has moderate permeability. :) !
A stable, nonmagnetic austenitic alloy steel having extremely low magnetic permeability especially in the unannealed condition, and consisting essentially of, in percent by weight, carbon 0.35 to 0.45, manganese 14 to 16.5, phosphorus 0.05 max., sulfur 0.07 to 0.12, silicon 0.55 to 1.15, nickel 3.5 to 5.5, nitrogen 0.12 max., chromium, 0.50 max. and the balance iron and incidental impurities.
permeability
The porosity directly correlates with the permeability because the permeability requires a certain level of porosity for a certain measure of it.

permeability
1. The permeability results might be localized due to excavation. 2. Lateral permeability not considered which may lead to erroneous estimate of field permeability.
Permeability refers to the ability of a material to allow fluids or gases to pass through it. It is influenced by factors such as the size of the pores in the material, the composition of the material, and the pressure applied. Permeability is an important property in various fields such as geology, engineering, and biology.
